Xandra baked 35 macarons and wafers. She burnt 2 pieces and counted the remaining pieces.
13 of the wafers and
34 of the macarons were apricot flavoured. There were equal number of wafers and macarons that were blueberry flavoured.
- How many unburnt blueberry macarons were there?
- What fraction of the unburnt pastries were apricot macarons?
(a)
Number of pastries that was not burnt
= 35 - 2
= 33
Fraction of the wafers that was blueberry flavoured
= 1 -
13 =
23 Fraction of the macarons that was blueberry flavoured
= 1 -
34 =
14 The number of blueberry wafers and blueberry macarons was the same. Make the numerators the same.
23 Wafers =
1x24x2 Macarons
23 Wafers =
28 Macarons
Number of unburnt wafers = 3 u
Number of unburnt macarons = 8 u
Total number of unburnt pastries
= 3 u + 8 u
= 11 u
11 u = 33
1 u = 33 ÷ 11 = 3
Number of unburnt blueberry macarons
= 2 u
= 2 x 3
= 6
(b)
Number of unburnt apricot macarons
= 8 u - 2 u
= 6 u
Unburnt apricot macaronsTotal unburnt pastries =
63 + 8 =
611 Answer(s): (a) 6; (b)
611
